Title: A servo power steering device for motor vehicles
IPC: B62D1/16
Filed: 1962-09-05
Abstract: 983,999. Vehicle telemotor steering. FAWICK CORPORATION. Sept. 5, 1962 [Sept. 5, 1961], No. 34001/62. Heading B7H.  In a double acting telemotor power steering system with a master cylinder 10 connected hydraulically to a slave cylinder 37, when master cylinder piston 17 is moved manually by wheel 22 open centre valve 42 is also moved to supply pressure fluid from source 57 to one side of piston 17, to render captive the fluid between the other side of piston 17 and one side of slave cylinder piston 38 and to connect the other side of piston 38 to sump 56. The open centre valve spool 43 is rotatably mounted on piston rod 15 and is normally centred by springs 47 (Fig. 1) when pressure fluid from the pump returns through passages 50, 51 to the sump. When rod 15 is rotated, for example, anticlockwise by hand wheel 22, due to the resistance to motion of the piston 17 the rod with valve spool 43 moves to the left and pressure fluid then passes from the valve through passage 60 (Fig. 6), check valve 63 and passage 64 to chamber 33 of cylinder 10 and moves piston 17 to the right. Fluid from chamber 34 passes through passage 24, valve 66<SP>1</SP> and passage 78<SP>1</SP> to the slave cylinder moving piston 38 to the right and fluid from slave cylinder chamber 36 is displaced through passage 78, valve 61 and passages 51 and 59 to sump 56. Normally-closed ball valve 72 is opened by the pressure differential between the faces of valve plunger 70 and normally open valve 66 is closed by the pressure differential between its opposite faces. Fluid leakage from the system is made up by fluid passing through check valve 88 or 88<SP>1</SP> and should the pressure fluid supply cease valves 66 and 66<SP>1</SP> only will remain open and the system will act as a simple telemotor. Specification 859,813 is referred to. Reference has been directed by the Comptroller to Specification 911,340.
